I got a free freezer, which I was going to gut and use for a fermentation chamber for beer. It's insulated, and would work with a thermostatic timer hooked to a heat lamp.
When I got it home, it looked so nice, I plugged it in. It dropped 20 F. in fifteen minutes. Compressor was humming along. I thought I would just leave it run and come back in the morning and see how it did. Good thing I stayed another ten minutes. At twenty minutes, it started a melodic hum hum about every ten seconds. All of the coils on the back of the freezer and compressor would move with the hum hum. It is a Sanyo, a small upright, about 4.5 feet tall and 2 ft. square in the other dimensions. It has the grid shelves that the refrigerant flows through. A black array of tubing on the back.
I unplugged it, and figured I would try it again tomorrow, but wanted to ask here if anyone here can tell me what this might be. It was free, and if I take all the shelves out, it will make an acceptable compartment to maintain a 70 degree plus or minus atmosphere for fermenting. I just don't want to trash it if it is something little, and I can get it fixed and maybe make a few bucks on it.
Ran fine and cooled for fifteen minutes. At twenty, started hum hum and shudderhum shudderhum.
